These pumps are not for use in PV-direct applications. You must either use a battery or AC power to power the pump.

Flowlight Booster Pump

Use DC or AC power to pressurize
water. Provides 3-4.5 Gallons per Minute (10-17 lpm) at pressure as high
as 65 PSI (4.5 kg/sq. cm) from shallow water sources.

The Flowlight Booster Pump provides city water pressure, anywhere. It
has been a standard in home renewable energy systems since 1986. It
is economical for domestic water supply, drip irrigation, and water
purification.

A booster pump is far more cost effective than
an elevated tank, providing pressure equivalent to over 100 feet (30m)
of elevation.

This DC pump uses one third to one half the energy
of a conventional AC pump, and eliminates the high starting surges that
push inverters to the limit.

It is more powerful, quieter, and much more durable
than plastic RV/Marine pumps.

Wearing parts are replaceable, and typically last
5 to 10 years. Overall life expectancy is 15 to 20 years.

Its complete instruction manual and Easy Installation
Kit make this pump simple for anyone to install and service, with no
previous experience

"Over the last five years, we've found our
Flowlight pump to perform impressively. If installed properly and filtered,
they are very faithful pumps." --- J.T., Nemia Valley, British
Columbia, Canada

"Our (Flowlight Booster Pump) has had 2 1/2
years of daily use. I have no complaints at all. It works really fine."
--- G.O., Willow, Alaska

"It's a delight to be weaned from the generator."
---C.H., Coulterville, California

Capacity

Note: Suction capacity may be further limited by intake pipe friction. Excessive
suction causes cavitation (vapor bubbles) creating noise and
excessive wear. Intake piping should be 1 inch or larger. Pump should be mounted
as close to the water source as possible.

Installation
* Pump may be mounted horizontally or vertically.
* Pump must not be submerged
* It may be placed inside a 6-inch (120 cm) or larger well casing, suspended
by a rope. If casing is smaller than 10 inches, request "adapting elbows"
instead of flex hoses

Pressure tanks serve two useful purposes. First, when pumps move water, they tend to create a pulsing effect on the flow. So when you go to turn on your faucet, the water can sort of jiggle back and forth, which can be annoying. A pressure tank eliminates the pulsing effect. The second reason is that the tank reduces the number of on/off cycles of the pump. With a properly sized pressure tank, the tank will be able to handle enough volume of water and pressure such that the pump won't have to turn on every time one turns the water on. For example, one could wash one's hands and the amount of water it would take would only reduce the pressure a slight amount and the pump wouldn't need to turn on. By reducing the amount of on/off cycles for the pump, the life of the pump is extended.
